This patchset aims to expand the cgroup_lib shell library to simplify
and centralize the whole mounting and cleanup process that can get
rather confusing and redundant when writing cgroup controller tests from
a shell environment. This is done by having the shell library make calls
to the C cgroup API from a binary utility.
In this patch set there are a few tests that have been extensively
rewritten to work with the new test API and to use the new functionality
from the cgroup lib. Because the test Cgroup lib handles mounting for v1
and v2 controllers, some tests were modified to also work under cgroup
v2. Some tests that were written for v1 controller also effictively test
v2 controllers, while others were written to test v2 controllers in the
spirit of the test or skipped outright.
